I block the entire cn TLD (and the RU, PK, Top, biz, info, and IN TLDs) and haven’t had any issues.
I also go a step further and block all IPs in those geolocations in my Router.
My wife and I each take a lot of random photos and screenshots and things we don’t want to share with each other (and we probably don’t want to be bothered with each other’s random stuff), so we don’t want to just do something like turn on Partner Sharing on Google Photos.
You can specify what gets shared with partner sharing. My wife and I have partner sharing set up so that it automatically shares photos of our kids with each other but not anything else.
Cloudflare will host videos at $5 per 1000 minutes and an extra $1 per 1000 minutes watched per month.

That’s the only Cloudflare approved way to do videos and images through the proxy
Turn the lights off, get the room as dark as possible, and point you phone camera at it.
Your phone camera can see IR lights as purple (apparently newer iPhone may have an IR filter).
If it’s a hidden camera AND it has night vision then you’ll see purple lights.

Can they? Theoretically is possible. In all likelihood however it’s not feasible.
The biggest concern you should have if you aren’t port forwarding is a router exploit. If your router is past end of life then the manufacturer may not be providing any more security updates for it and that could leave it vulnerable.
TP-Link a few years ago refused to patch some older routers that had an exploit because they were 10 years old. So, it happens.
Google your router name/model number and exploits to see if anything exists for it. If not then you’re fine.
It all comes down to “what are you trying to do.”
Not everyone runs applications, so docker is not the answer to everything.
But if you only have 8Gb of RAM and are trying to run VMs then I’d advise you to go buy more RAM.
In short cloudflare is both a DNS server and a reverse proxy. When you add a DNS record in there and mark it as proxy cloudflare will publish the DNS record but will instead give its own IP as the destination.
When a visitor enters your URL instead of getting your IP they will be given Cloudflare’s IP. The visitor will then send their web request to Cloudflare. Cloudflare will then send that request to your actual IP.
That’s the basic version. However, Cloudflare’s position as a proxy gives it the ability to inspect and act on traffic as a WAF, blocking traffic that meetings the IDS/IPS rules.
